Software Operation

Advanced Conguration: If you have more than one Router installed you will want to check this box.

Router Type: Select “Cat Switch”

A/V Split: Check this box if you need to route audio and video independently, regardless from

which source they originated from. Leave unchecked if you want audio and video

signals from the same input to remain together.

For example, if you wanted to route dierent video feeds to dierent locations but wanted all of them to have the

same audio, you should check the box.

Find the Installation CD that came with your CATXPro unit. This CD has the SmartControlPro software that you will

need in order to control the unit using a computer.

Insert the CD into your CD-ROM. On the CD you should see:

• SmartControl Pro Installer.exe

• SmartControl Pro Help File

• CATXPro Manual in PDF format

Double click SmartControlPro.exe in order to initiate software installation. Click Install. After installation has

completed, click CLOSE.

In order to use the software, click on the START button>Programs>SmartControl Pro. There you should see a help le,

the SmartControl Pro launcher as well as a shortcut to uninstall SmartControl Pro. Click on SmartControl Pro in order to

launch the software.

When the software starts you will see a screen like this.

www.smartavi.com

Inputs/Outputs: Enter the number of Inputs/Outputs your CATXPro has. For now, although the CATXPro can

have up to 64 inputs and 64 outputs, we will assume that there are 16 inputs and 16 outputs.

Com Port: Select the appropriate com port that your computer is using to access the router.

Router Time out: By default this is 0 meaning the computer acknowledges commands almost instantly.

Sometimes a computer takes longer to respond. This setting should be left at 0. If you need to

change it, it should be no higher than 0.2.

After you have entered in the necessary information click OK. This will now take you to the Main Routing Window

where you can route the dierent video/audio connections.

On this screen you will notice the input buttons running down the left side while the output buttons run across the

top. They are each labeled 1 through 16.

Note: The three small colored buttons at the lower right labeled ALL, VIDEO, and AUDIO are not available if AV Split

was not checked when you congured your router.

Main CATXPro window

Software Operation (continued)

www.smartavi.com

The Main Routing Window enables you to control the router(s) connections by means of the CATXPro panel, the

button panel, or with pre-recorded routes called macros.

CATXPro Panel: This is probably the simplest way to route the connections. Simply click on the cross point itself. The

input on the left will then be routed to the output above.

Note: Inputs can be routed to several dierent outputs, but each output can only have a single input at any one time.

So you can have several connections horizontally but not vertically.

The Button Panel: These are the numbered buttons across the top and left sides. Click an output button on the top,

and then click an input button on the left.

Options for using the Button Panel

• Output Options:

To select multiple outputs next to each other, click on one output, then hold the shift key down and click the last

output. When the input is clicked, it is routed to all selected outputs.

To select multiple outputs individually, hold the control key down and click on any number of outputs. When the

input is clicked, it is routed to all selected outputs.

• Input Options:

To route an input to all the outputs at once, hold the control key down and click on an input.

To leave the outputs selected after the route is made, hold the shift key down and click on an input.

Software Operation (continued)

www.smartavi.com

Macros: This section of the window is used to save and play back macros. Macros store a set sequence of routes.

To record a macro:

1. Click on the Record button (last button shown above). A blinking “recording” message below this button will be

displayed to indicate that all routes are being recorded.

2. Select the desired cross points. (See CATXPro Routing for details on making these routes.) There is no limit on the

number of routes you may record.

3. If you click a macro button while in the record mode, the macro will be executed, and these routes will be added

to the recording. This makes it possible to combine the routes of two or more macros into one bigger macro.

4. When nished, click the “Save Macro” button. You will be instructed to then click on one of the macro buttons.

Doing this will save the recorded routes to that button.

To cancel saving the macro, click the “Cancel Save” button.

5. To play back a macro, simply click on one of the 50 macro buttons. Use the scroll bar to bring any of these into

view.

6. The macros are automatically saved in the current conguration le. They are also saved when you select the File/

Save Conguration... menu.

To save macros in a separate le for a special purpose, select the File/Save Macros...menu.

Controlling with IR

Switching Ports with Remote Control

You have the option of controlling the CATXPro via Remote Control. The remote is used to control the CATXPro. The

SM-EYE must be connected to the CATXPro ( this is an optional connector not always available in all boxes) in order to

interface the remote control with the matrix. The way the remote control the matrix is as follows:

Xx<enter>yy<enter>

When XX is the output , YY is the input

To change the routing of the signals,

For example, to set output 3 to input 2 press “0” + “3” + ENTER, then press “0” + “2” + ENTER. If a wrong button is

pressed, the user must either press the ESC button or wait 5 seconds before restarting the sequence.
